I am going to create Win Hex like application in Qt. I want to know which widget should I use for creating hex display area. I have to open hard disk in it so it would be a very large number of lines for displaying 500 GB of disk.
So, which widget can handle this large number of hexadecimal lines?
I have started to do it in QWidget's paint event but the height of QWidget is in integer so number of lines could not be greater than the range of integer.
QWidget
So, should I use QTextEdit or QPlainTextEdit?
QTextEdit
QPlainTextEdit
You use wrong way. Consider to use QAbstractItemModel + QTableView. Your model can use "virtual window". It means that your model holds only small piece of data which will be loaded on demand.
